Simultaneity - Albert Einstein and the Theory of Relativity

Imagine two observers, one seated in the center of a speeding train car, and another standing on the platform as the train races by. As the center of the car passes the observer on the platform, he...

I agree with this statement although astro-physics requires this type of unit for calculations in distance and the speed of light unit of measurement is alot better then writing so many zero's behind the numbers.But thats all i fear it is good for!

The equation is set up such that the more you accelerate an object, its mass increases such that it requires exponentially more energy to accelerate a little more each time. For example, say we simplify the speed of light at 300000 km/s, then at the very end, it will go 299999, then 299999.9, then 299999.99, 299999.999, and so on, so you can see how it never reaches the actual limit, yet is still accelerating indefinitely.

How would they tell speed of light or faster than speed of light?

Speed limit is there because it is observed that the speed of light is constant, always, for everyone.

Imagine standing by the road, and a car that moves at a constant speed of 200 km/h passes you by.

You hop into your Ferrari and try to catch that car. But no matter what you do, whenever you look at that car in front it's still moving away from you at a constant 200 km/h. In another words, you can never move faster than that car.

in order to make speed of light as constant
so that space bend
so time get slow
results
so that atomic bomb is possible
so that no intersteller travel is possible

"Speed of light is constant" is not some ad-hoc postulate Einstein made up because had a strange idea that no one should be able to move faster than light.

The constancy of the speed of light was first experimentally observed 120 years ago. It is a well established fact, and anyone that questions this fact must first provide the evidence. I'm not saying that is an impossible task, but saying "I don't feel that's true" just doesn't cut it.

we use light as measurement
that is why

but actually
space time constant

light vend how could it be constant

fission is energy dissipitating
fusion is not chain reaction

gravity is created by spinning plasma

if you can accelerate continuously
you can be faster than speed of light

I agree that in a "Vacuuuuum" the speed of light is constant in a normal enviroment ! Thank God i am a "Human " and was born with an ability to "CHEAT!!!!!! The idea of cheating somehow can be observed by looking at the data from experiments into fluid dynamics and the quest for absolute zero. It has been observed that a bose /einstein state is achieved very close to "ZERO" and that these supercooled atoms occupy more then one space time constant and are not bound by the speed of light boundary.
